我有一个选择007的E8257C,我很难过,当我在斜坡模式下扫描时,我得到一个错误508 Frac N解锁。
主要是1-3GHz是我可以复制故障的频率范围。 我认为这可能与服务说明E8257C-15有关。 我已经取代了Frac N.我已经进行了调整。 我升级Fw包括选项,我尝试重新加载或执行cal常量的恢复,认为可能是损坏的数据,然后重新进行TME调整。 这不会在步骤扫描或列表中产生任何类型的错误。 在相同的频率范围内。 但在步骤中我可以看到Freq是不正确的。 从我看到的情况来看,变量预标量上有一个切换点。 我正在使用实时规范。 我可以将扫描速度降低到2秒仍然在斜坡上,但这是我在保持解锁错误时最慢的速度。 我可以看到一个看起来像FMing的切换点。 再次,这似乎与服务说明E8257C-15有关。 我已经阅读了足够的知道在RAMP模式下不使用采样器所以这给我留下了Frac N,Reference assy或YIG驱动程序。 任何想法将不胜感激。 Joe L编辑:jlubecky于2013年9月18日下午1:20编辑:jlubecky于2013年9月18日下午2:11 以上来自于谷歌翻译 以下为原文 I have an E8257C with opt 007 and I am stumped I am getting an error 508 Frac N unlocked when I sweep in ramp mode. mainly 1-3GHz is the freq range I can duplicate the failure. I thought this may be related to the service note E8257C-15. I have replaced the Frac N. I have run the adjustments. I upgraded Fw including options, I tried reloading or doing a restore of cal constants thought maybe corrupt data, then reran TME adjustments. This doesn't give any kind of error in step sweep or list. over same freq range. But in step I can see Freq is incorrect. From what I'm seeing it looks like there is a switching point on the variable prescalar. I am using a realtime spec an. and I can slow down the sweep down to 2 second still in ramp but this is the slowest I can go while maintaining the unlock error. I can see a switching point that looks like its FMing. again this really seems like its related to the service note E8257C-15. I have read enough to know the sampler is not used when in RAMP mode so this leaves me with Frac N , Reference assy, or YIG driver. any ideas would be greatly appreciated.

嗨乔 - 您看到的问题看起来与固件错误有关。
我附上了与此问题相关的服务说明,首先检查仪器的固件是否为C.03.31和C.03.41,因为您没有提及仪器的固件。 如果您需要升级仪器的固件,请点击以下链接: - http://www.home.agilent.com/agilent/editorial.jspx?cc=MY&lc=eng&ckey=1000000797:epsg:sud&nid = -536906709.749304.02& id = 1000000797:epsg:sud& cmpid = z***indss_firmware E8257C的最新固件为C.03.85 http://www.home.agilent.com/agilent/software.jspx?cc=US&lc = eng& nid = -536906709.749304.02& id = 1217917问候 - 以上来自于谷歌翻译 以下为原文 Hi Joe - The problem that you are seeing looks like related to firmware bug. I’ve attached the Service Note related to this issue, which is first to check the firmware of your instrument whether it’s C.03.31 and C.03.41 since you didn’t mention the firmware of your instrument. If you need to upgrade the firmware of your instrument here’s the link:- http://www.home.agilent.com/agilent/editorial.jspx?cc=MY&lc=eng&ckey=1000000797:epsg:sud&nid=-536906709.749304.02&id=1000000797:epsg:sud&cmpid=z***indss_firmware The latest firmware for the E8257C is C.03.85 http://www.home.agilent.com/agilent/software.jspx?cc=US&lc=eng&nid=-536906709.749304.02&id=1217917 Regards - 附件 |

醉狼工作室 发表于 2018-12-3 10:31 该单元已经拥有最新的Rev C.03.85我已通过LAN和GPIB进行FW升级,以确保更新RAMP SWEEP YIG DRIVER FPGA。 我犯了同样的错误。 你认为有缺陷的YIG DRVIER组合可以做到吗? 我真的被困在这里了。 任何想法将不胜感激。 以上来自于谷歌翻译 以下为原文 The unit already has the latest Rev C.03.85 I have run the FW upgrade both over LAN and GPIB just in to ensure the RAMP SWEEP YIG DRIVER FPGA was updated. I get the same error. Do you think a defective YIG DRVIER assy could do this ?? I am really stuck here. Any ideas would be greatly appreciated. |
